Suppose someone argues that since adults are persons now they must have also been persons when they were fetuses, and since it is wrong to kill a person, it would be wrong to kill a fetus. What is the most problematic feature of this argument?

The correct answer is: Weak analogy.

Explanation:

A weak analogy is a fallacy -statement given with no proven support- in which individuals compare their ideas to others to justify their thoughts as correct but in most of cases the comparisons are mistaken or vague and were selected by those individuals so that others could accept their beliefs.

In the example, fetuses are compared to human beings in the attempt to support that if killing humans is penalized so it should be killing fetuses. Though, the topic of abortion is more complex than that. The conditions under which the pregnant woman got pregnant are diverse and should be analyzed carefully and in deep.
